Controller Cable

The FiTECH Fuel Injection Controller Cable (FIT60014) is a precision transmission controller cable designed for automatic transmission systems requiring reliable data communication between the engine management computer and transmission control module. This rubber-coated cable assembly is engineered for mechanics and enthusiasts performing modern fuel injection conversions or transmission controller retrofits on both stock and modified vehicles. The controller cable serves as the critical signal pathway that enables your fuel injection system to coordinate with automatic transmission shifting logic, ensuring smooth gear transitions and optimal engine performance under all driving conditions.

Constructed with a protective rubber coating, this transmission controller cable resists vibration-induced damage, heat degradation, and corrosion that commonly plague underhood wiring in high-performance applications. The black rubberized jacket shields the internal conductors from electromagnetic interference while providing secure routing through the engine bay without requiring additional conduit or loom protection. FiTECH's design ensures signal integrity at idle and under full throttle, where transmission shift timing demands are most critical—poor cable shielding or damaged connectors can result in delayed shifts, limp-mode failures, or transmission hunting between gears that degradates both drivability and fuel economy.

The controller cable is ideal for builders integrating FiTECH fuel injection systems into classic cars, street rods, and restomod projects where modern automatic transmissions replace original manual or outdated transmission control systems. Installation requires secure routing away from high-heat sources (exhaust manifolds, turbo discharge pipes) and proper connector seating at both the ECU and transmission controller—any loose connector will trigger fault codes and transmission malfunction lights. Technicians working on late-model LS engine swaps, Coyote conversions, or standalone fuel injection tuning will find this cable kit essential for achieving seamless engine-to-transmission communication that factory integrations depend upon.
